Description

System message acquisition, indication method, device and device

Technical field

The present invention relates to the field of communications, and in particular, to a system message acquisition, indication method, apparatus, and device.

Background technique

A user equipment (User Equipment, UE) of the Machine Type Communication (MTC) type needs to acquire a system message broadcast by the serving cell every time the base station is accessed or wakes up from the sleep state to confirm the base station. Whether the system message of the corresponding serving cell has changed. This requires a large amount of power consumption of the user equipment, and the Long Term Evolution (LTE) MTC requires the user equipment to achieve low power consumption. Therefore, the manner of acquiring system messages needs to be improved.

In the related art, the E-UTRAN Node B (eNB) sets the indication information in the Master Information Block (MIB) to 1 when the system message of the serving cell changes, and the user equipment is used each time. Accessing the base station or acquiring the MIB broadcasted by the serving cell every time when waking up from the sleep state, reading the indication information in the MIB. If the indication information is 1, the user equipment determines that the system information for the MTC technology cannot be skipped. The system information block Type 1 - Bandwidth Reduced (SIB1-BR) continues to acquire the SIB1-BR. If the indication information is 0, the user equipment determines that the SIB1-BR can be skipped. Among them, skipping means not reading.

The user equipment wakes up frequently or frequently moves between cells, causing the user equipment to frequently read system messages (such as SIB1-BR), resulting in a large power consumption of the user equipment.

Summary of the invention

In order to solve the problem that the user equipment needs to frequently read the system message when the user equipment wakes up frequently in the serving cell, or frequently moves between the cells, and the power consumption of the user equipment is high, the embodiment of the present invention provides a system message acquisition, Indicates methods, devices, and equipment.

The user equipment determines, according to the first indication information sent by the first network device, whether to skip the first system message or re-acquire the first system message, and does not need to frequently acquire the first system message each time the base station is accessed or wakes up from the sleep state. Or, the first system message is not frequently acquired each time the cell is reselected to the target cell, which reduces the power consumption and access delay of the user equipment.

In a possible implementation, the user equipment skips the first system message according to the first indication information, or reacquires the first system message according to the first indication information, including: when the first system message is adjacent to the first cell When the system message of the second cell is used, the user equipment skips the first system message when reselecting to the second cell according to the first indication information, or reacquires when reselecting to the second cell according to the first indication information.

The first system message may be a system message of the first cell, or may be a system of the second cell adjacent to the first cell. The first message corresponds to the first network device, and the methods for obtaining and indicating the two first system messages are respectively introduced below.

Referring to FIG. 4, a flowchart of a method for acquiring and indicating a system message according to an embodiment of the present invention is shown. The first system message is a system message of the first cell, and the system message obtaining and indicating method may include:

Step 401: The first network device determines first indication information corresponding to the first system message, where the first system message is a system message of the first cell, and the first cell corresponds to the first network device.

The first cell may be the current serving cell of the user equipment.

The first indication information is used to indicate that the user equipment skips the first system information, or the first indication information is used to indicate that the user equipment reacquires the first system message.

Step 402: The first network device sends the first indication information to the user equipment.

Optionally, the sending duration of the first indication information is N periods, where the period is a modification period (MP) or a discontinuous reception (DRX) period or an enhanced discontinuous reception (enhanced DRX, eDRX) period. Optionally, the first system message is unchanged in N cycles; optionally, the result of the modulo operation of the initial system frame number of the first indication information to the N cycles is 0.

In the related art, when the first system message of the first cell changes, the first network device sets the first indication information to 1, and starts the timer Timer, and assumes that the duration of the timer is X hours, that is, the first indication. When the information is set to 1 for X hours, when the timer expires, the first network device sets the first indication information to 0, please refer to FIG. 5.

When the timer expires, the first time A network device sets the first indication information to 0, please refer to FIG. 6. If the user equipment wakes up after acquiring the first system message within X hours, and wakes up from the sleep state within X hours, the user equipment needs to re-read the first system message when waking up, resulting in multiple user equipments. Get the same first system message twice, and the power consumption is higher.

In the prior art, the first system message does not change in a modification period, but can only change at the boundary of the modification period. As shown in FIG. 7, the first cell in the first cell in the MP(n) transmits the original first system. The message, the updated first system message is sent within MP(n+1), and then the updated first system message is sent. The modification period is m and satisfies SFN mod m=0, where SFN is the system frame number, and the range is 0-1023, which is a simple note, and m is a positive integer. Thus, the boundary of the modification period is known to the user equipment, for example, m=256, and the change of the first system message may start at SFN=0, SFN=256, SFN=512, SFN=768.

In this embodiment, X hours can be set to N periods (Period), which is denoted as NP, that is, the length of N periods, that is, the first period in which the first system message is changed (or not skipped) is sent within the NP duration. An indication information, for example, a first indication information indicating that the first system message has changed (or not skipped) is set to "1", and conversely, a first indication indicating that the first system message has not changed (or skipped) The information is set to "0"; the meaning of "1", "0" can be interchanged. Optionally, the first indication information starts to send “1” in the SFN that satisfies SFN mod NP=0, and “1” is sent in M cycles, where “1” indicates that the first system message changes or does not skip, “0” ” indicates that the first system message has not been changed or skipped, or the meanings of “0” and “1” are interchanged, so that the user equipment knows that the first indication information is set to the start time and the end time of “1”. Since the first system message update is very infrequent, it can be restricted that the first system does not change in the first system within the NP. In this way, the user equipment only needs to read the first system message once in an NP, and the NP after the boundary of the NP end is set by the user. The device only needs to check the first indication information. If the first indication information is "1", the user equipment re-reads the first system message. If the first indication information is "0", the user equipment does not re-acquire the first system message. Since the user equipment only needs to read the first system message once in one NP, the power consumption of the user equipment is saved.

It should be noted that, if the first system message needs to be updated, the first cell sends a paging message to the previous MP of the MP that starts sending the updated first system message, where the paging message carries the update indication information to indicate the user. The device first system message will send a change, so that all user equipment needs to reacquire the first system message from the next MP start time.

In this embodiment, the first indication information is carried in the DCI or paging message of the paging message or the MIB of the first cell or the MIB of the second cell.

Step 403: The user equipment receives the first indication information sent by the first network device corresponding to the first cell.

It should be noted that, in the user equipment, the first system message is stored at this time. When the storage time of the first system message does not exceed the preset duration, the first system message is valid, and then the first indication information is received. And when the first indication information is used to indicate that the user equipment reacquires the first system message, the user equipment deletes the stored first system message. The first system message is invalid when the storage time of the first system message exceeds a preset duration. The preset duration may be 24 hours or other durations, which is not limited in this embodiment.

Step 404: The user equipment skips the first system message according to the first indication information, or reacquires the first system message according to the first indication information.

In summary, the system message obtaining and indicating method provided by the embodiment of the present invention, the user equipment determines, according to the first indication information sent by the first network device, whether to skip the first system message or re-acquire the first system message, without The first system message is frequently acquired each time the base station is accessed or wakes up from the sleep state, or the first system message is not frequently acquired each time the cell is reselected to the target cell, which reduces the power consumption and access delay of the user equipment.

Referring to FIG. 8, a flowchart of a method for acquiring and indicating a system message according to an embodiment of the present invention is shown. The first system message is a system message of the second cell that is adjacent to the first cell, and the system message obtaining and indicating method may include:

Step 801: The first network device determines first indication information corresponding to the first system message, where the first system message is a system message of a second cell that is adjacent to the first cell, where the first cell corresponds to the first network device.

The corresponding explanations are detailed in the descriptions in the embodiments shown in FIG. 3 and FIG. 4, and are not described herein.

Before the user equipment is reselected to the second cell, the first cell is the current serving cell of the user equipment, and the second cell is the neighboring cell of the first cell; after the user equipment is reselected to the second cell, the second cell is the user equipment Current serving cell.

When the first network device determines the first indication information corresponding to the first system message, the first network device first sends the second network device to send The first message; and determining the first indication information according to the first message. The first message is a first system message or the first message is used to indicate whether the first system message changes or the first message is used to indicate whether to skip the first system message, and the second network device corresponds to the second cell.

When the first message is the first system message, the first network device reads the stored first system message, and compares the received first system message with the stored first system message, when the first message is received. When the system message is different from the stored first system message, generate first indication information for indicating that the user equipment reacquires the first system message when reselecting to the second cell, when the received first system message and the stored When the system messages are the same, the first indication information for indicating that the user equipment skips the first system information when reselecting to the second cell is generated.

When the first message is used to indicate whether the first system message changes, the first network device generates first indication information for indicating whether the first system message changes; when the first message is used to indicate whether to skip the first system When the message is received, the first network device generates first indication information for indicating whether to skip the first system message according to the first message.

The first indication information is carried in the DCI or paging message of the paging message or the MIB of the first cell or the MIB of the second cell. Taking the first indication information in the MIB of the first cell as an example, the first network device may generate a first indication for indicating that the first system message changes or for indicating that the user equipment is prohibited from skipping the first system message. When the information is set, the value of one bit in the MIB may be set to "1", when generating the first indication information indicating that the first system message has not changed or is used to indicate that the user equipment skips the first system message, The value of one bit in the MIB can be set to "0". The meaning of the value of 1 and 0 may be interchanged, or the value of the bit in the MIB may be set to other values, which is not limited in this embodiment.

When the first system message of the second cell changes, the first network device may indicate the change in the second system message of the first cell, which may cause a change of the second system message. When the second system message of the first cell is changed, the first cell sends a paging message. Since the paging message indicates that the user equipment acquires the second system message, all user equipments need to reacquire the second system message. When the first indication information is carried in the MIB of the first cell, the user equipment may obtain the first indication information. That is, when the first indication information is carried in the MIB and the first indication information is used to indicate whether the first system message changes or the first indication information is used to indicate whether the user equipment skips the first system message, by the first A change in the MIB caused by a change in the indication information triggers the paging.

Step 802: The first network device sends the first indication information to the user equipment.

Optionally, the sending duration of the first indication information is N periods, where the period is a modification period or a DRX period or an eDRX period; optionally, the first system message is unchanged in N periods; optionally, the first The result of the modulo operation of the initial system frame number indicating the information transmission for N cycles is zero.

The description of the transmission duration is detailed in the description of the embodiment corresponding to FIG. 4, and details are not described herein.

In this embodiment, the user equipment is a user equipment that stores the first system message, and the storage time of the first system message does not exceed the preset duration. If the user equipment does not store the first system message, the user equipment does not pay attention to the change of the first system message; if the storage time of the first system message exceeds the preset duration, the first system message is invalid, and the user equipment may A class user device is considered to be a user device that does not store the first system message.

Step 803: The user equipment receives the first indication information sent by the first network device corresponding to the first cell.

It should be noted that the first system message is stored in the user equipment. If the user equipment stores the first system message of the first cell, when the user equipment finds that the first system message changes or cannot skip, the first system message is re-acquired, otherwise, the first system message is skipped. If the user equipment stores the first system message of the second cell, when the user equipment reselects to the second cell and finds that the first system message changes or cannot skip, the first system message is re-acquired. Otherwise, skip the first system message.

When the storage time of the first system message does not exceed the preset duration, the first system message is valid, then, when the first indication information is received and the first indication information is used to indicate that the user equipment reacquires the first system message The user equipment deletes the stored first system message.

Step 804: The user equipment skips the first system message when reselecting to the second cell according to the first indication information, or reacquires the first system message when reselecting to the second cell according to the first indication information.

The user equipment skips the first system message when reselecting to the second cell according to the first indication information, or reacquires the first system message when reselecting to the second cell according to the first indication information, including:

or,

In summary, the system message acquisition and indication method provided by the embodiment of the present invention, when the first indication information indicates that the first system message changes or the user equipment is re-acquired to obtain the first system message, the user equipment reacquires the first system message. The accuracy of the first system message stored in the user equipment is ensured; when the first indication information indicates that the first system message does not change or the user equipment is instructed to skip the first system message, the user equipment skips the first system message. Reduce the power consumption and access delay of user equipment.
